2 Inch Silicone O-Ring For Industrial Hydraulic

A 2-inch silicone O-ring is a precision-engineered sealing component built for hydraulic systems that require stable performance under varying pressure, temperature, and fluid conditions. Known for its excellent elasticity and thermal resistance, silicone material ensures dependable sealing across industrial hydraulic applications, including fluid control systems, filter housings, and cylinder interfaces.

The 2-inch silicone O-ring is designed for both static and dynamic hydraulic sealing. Its flexibility enables it to adapt smoothly to mating surfaces, preventing fluid leakage and maintaining pressure stability. With enhanced temperature performance and durability, this O-ring is ideal for use in industrial plants, heavy equipment, and mechanical systems requiring long-term sealing reliability.

Engineered with tight dimensional tolerances, it guarantees consistent fitment in standard hydraulic fittings and delivers stable performance under repeated compression cycles.

Wide Temperature Tolerance

Silicone O-rings operate reliably from -60°C to +230°C, making them suitable for cold-start systems or high-temperature hydraulic circuits.

Excellent Flexibility & Compression Resistance

Silicone maintains its sealing force even after long-term compression, reducing leakage risks during continuous operation.

Stable Hydraulic Performance

While silicone is not ideal for petroleum-based oils, specialized formulas offer improved performance in selected hydraulic fluids. It provides superior thermal stability compared to NBR in high-temperature systems.

Aging, Ozone & UV Resistance

Ideal for hydraulic equipment used outdoors or in exposed conditions, delivering long service life without cracking or hardening.

Clean & Non-Toxic Material

Silicone is chemically inert and suitable for systems requiring minimal contamination and high cleanliness.
